A proof of concept 3D printed planar inverted F antenna (PIFA) using Aerosol Jet Additive Manufacturing technology is presented. The cellphone handset PIFA presented in [1] for the 800 and 1900 MHz bands is scaled to 36.5 and 74.5 GHz. The simulated results yield return losses of 17.8 and 20.4 dB at 36.5 and 74.5 GHz, respectively. The maximum theta-pol realized gain is 2 dBi at both frequencies,...
In this work, investigation has been made of a planar millimeter wave antenna on microfluidic channels which allow a very large resonance frequency tuning up to 51% (from 16.8 to 28.4 GHz). A microstrip antenna lays over a 12 mil (300 µm) thick liquid crystal polymer (LCP) substrate in which two micro-channels are drilled to be filled with different dielectric liquids (water, ethanol, methanol, acetone)...
This paper presents, for the first time, a tunable microstrip microfluidic bandpass filter, with a center frequency of 1 GHz, on liquid crystal polymer (LCP). A 60 mil cavity, initially filled with distilled (DI) water (εr = 80), is placed below a 2 mil LCP layer. Based on this multilayer structure, the dimensions of microstrip lines are determined. In order to tune the filter center frequency, DI...
This paper presents, for the first time, the integration of V-Band and W-Band antennas with SPDT switch on organic Liquid Crystal Polymer (LCP) substrate. A wideband chip to package wire-bond transition was designed so that the insertion loss is minimized. The antennas were designed and optimized for frequency operation at 57 and 80 GHz with a gain of 10.5 and 9.5 dBi. The gain, S11, E-plane and H-plane...
This letter presents a low-cost and lightweight transceiver with RF front-end components integrated on multilayer organic liquid crystal polymer (LCP) substrate for 60-GHz wireless communication applications. Two embedded dual-mode filters with an insertion loss of 3.1 and 2.4 dB are included, while they are designed to improve the isolation between the transmitting and receiving modes. A package-integrated...
